SYNOPSIS

nvme id-iocs <device> [--controller-id=<cntid> | -c <cntid>]
                        [-o <fmt> | --output-format=<fmt>]

DESCRIPTION

For the NVMe device given, send an identify command and return the Identify I/O Command Set data structure.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

OPTIONS

-c <cntid>
--controller-id=<cntid>

Retrieve the identify I/O Command set data structure for the given cntid. If this value is not given, cntid will be 0xffff.

-H
--human-readable

This option will parse and format many of the bit fields into human-readable formats.

-o <format>
--output-format=<format>

Set the reporting format to normal, json, or binary. Only one output format can be used at a time.

EXAMPLES

  • Have the program interpret the returned buffer and display the known fields in a human readable format: 

    # nvme id-iocs /dev/nvme0

  • show the fields in human readable format 

    # nvme id-iocs /dev/nvme0 -H
